The main object of this inventionis to provide ina spring structure improved br'ac-` ing means for supporting against lateral A further object is to provide a bracing means for cushion and like spring structures Which is eective in supporting the parts braced and does not materially' detract Afrom the resiliency of the body springs.-

invention is clearly illustrated in the'accompanying drawing in which Fig. 1 is a fragmentary plan spring cushion structure embodyingthe features of my invention.-

The braces 6 areV provided With-laterally the springs Within the'channel. The channel is Valso clamped upon ahelically .coiled coupling member 'l0 With which the laterally turned pintle-like portion 11 of the bra-ce vis j engaged.` This coupling member is engagedupon the brace before it is clamped Withinthe channel. The coupling member maybe u enf t gagedwith the portion 11 by rotatingthe coupling member or threadingit over the part l1.
